用法說明
How is "Quality" different from similar structures?What usage mistakes are common with "Quality"?
quality of + NOUN vs quality + ADJECTIVE
- quality of + NOUN 用於描述某個特定事物（名詞）的品質或特性。這裡的 "quality" 是名詞，意思是「品質、特性」。
- quality + ADJECTIVE 則是用形容詞來直接修飾名詞 "quality"，描述這是何種品質（如好、壞、高、低）。此時 "quality" 是名詞，但作為形容詞的修飾對象。
- 簡單區分：of 後面接的是「被評價的對象」，而形容詞則是「對品質本身的描述」。 EN: We need to improve the quality of our customer service. 翻譯: 我們需要提升客戶服務的品質。
EN:We are committed to providing quality customer service.
翻譯:我們致力於提供優質的客戶服務。
EN:The quality of the air in the mountains is excellent.
翻譯:山上的空氣品質極佳。
EN:This is a high-quality product that will last for years.
翻譯:這是一個能使用多年的高品質產品。
總結建議
一般來說，強調「某事物（名詞）的品質」時使用 "quality of + NOUN"，而將品質作為一個特徵來修飾名詞時則使用 "quality + ADJECTIVE" 或複合形容詞 "ADJECTIVE-quality"。

常見錯誤
What are common mistakes with "Quality"?Which "Quality" sentences look correct but are wrong?
×The product has many good qualities.
✓The product has good quality.
When referring to the general standard of something (uncountable), use 'quality' without 'a' or plural. Use plural 'qualities' only when listing distinct characteristics or traits of a person/thing.
×This is a quality product.
✓This is a high-quality product.
Using 'quality' directly as an adjective before a noun is informal or business jargon. For formal or academic writing, use 'high-quality', 'good quality', or 'of good quality' as a modifier.
×We focus on the quality, not the quality.
✓We focus on the quality, not the quantity.
'Quality' and 'quantity' are often confused because they sound similar and are both abstract concepts. 'Quality' refers to standard, while 'quantity' refers to amount.
×It is quality that matters most.
✓It is the quality that matters most.
When 'quality' is specified or singled out (e.g., followed by a relative clause like 'that matters'), it usually requires the definite article 'the'.
×We checked the quality for the product.
✓We checked the quality of the product.
The noun 'quality' is typically followed by the preposition 'of' to indicate what possesses that quality, not 'for'.
×We need to quality our products.
✓We need to improve the quality of our products.
'Quality' is a noun, not a verb. Do not use it as a verb. Use verbs like 'improve', 'ensure', 'check', 'maintain', or 'control' with 'quality'.
